Wash the rice, urad dal, and fenugreek seeds together. Soak them in
water for about 4-6 hours.
After soaking, drain the water and grind the rice, urad dal, and
fenugreek seeds together to form a smooth batter. Add water gradually
as needed while grinding. The batter should be slightly thick. Add
salt to the batter and mix well.
Allow the batter to ferment overnight or for at least 8 hours. The
batter will rise and become slightly airy.
Once the batter is fermented, mix it gently to get a uniform
consistency.
Heat a non-stick skillet or dosa pan on medium heat. Lightly grease it
with oil or ghee.
Pour a ladleful of dosa batter onto the center of the pan. Using the
back of the ladle, spread the batter in a circular motion to form a
thin dosa.
Drizzle a little oil or ghee around the edges of the dosa and cook
until the edges start to turn golden brown and crispy.
Flip the dosa using a spatula and cook the other side for a minute or
until it's cooked and slightly crispy.
Remove the dosa from the pan and serve hot with chutney, sambar, or
any desired accompaniment.
